Additionally, i would like to emphasize how important it is to carefully choose which method of authentication you select initially, because the only way to change it is to have a clean reinstall of Tableau Server. Tableau strongly advises that the authentication method you initially choose should be considered permanent. If you must modify the authentication method, be aware that Tableau Server will lose all associations between published views and the people who published those views; Tableau Server will no longer be able to filter published views by the publishers’ names.
